ABSTRACT:
An electromagnetic fan clutch having a radial flange adapted to be mounted to the fan drive hub of an internal combustion engine and an axial shaft connected to the radial flange. A fan hub, adapted to have a fan mounted thereto, is rotatably connected to the drive shaft adjacent to the radial flange. The radial flange has an axial hub spacing the fan hub from the flange portion of the radial flange a distance sufficient for the insertion of mounting bolts. An annular armature is connected to the fan hub by a plurality of leaf springs axially biasing the armature away from a stator. The stator is fixedly attached to the axial shaft and rotates therewith. A solenoid coil enclosed in a coil housing is disposed adjacent the stator. The coil housing is rotatably connected to the axial shaft and is held stationary by an anchor strap connected between the coil housing and a convenient stationary member in the engine compartment.
